There has been a lot of controversy about the air quality in Beijing for the Olympics... There are those who argue that the pollution has not improved and there continues to be a health risk for athletes while others report that the quality of the air in Beijing is vastly improved and clean-up measures by the city will guarantee a safe environment for athletes and spectators.
As for myself... I take no sides on the issue. I can neither confirm nor deny either side of the argument. The games are only 10 days away; only time will tell.
